Sometimes, when there is an obstruction or a broken spring keeping the door from opening or closing, the operator will run for an hour or two. This wears out the clutch so that it needs to be replaced.<\/p>\n\n\n\n<p>Occasionally, the clutch will become slippery from running for too long. If this is the case, rub the old clutch disk on a hard concrete floor. This should make it usable again, thus avoiding the need for an immediate replacement.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-medium-font-size\" id=\"h-installing-a-new-clutch\">Installing a New Clutch<\/h2>\n\n\n\n<ol class=\"wp-block-list\" start=\"5\">\n<li>First, put the pressure plate back in place.<\/li>\n\n\n\n<li>Install the new clutch disk.<\/li>\n\n\n\n<li>Then put the other components of the clutch assembly back in order:\n<ol class=\"wp-block-list\">\n<li>Pulley<\/li>\n\n\n\n<li>First washer<\/li>\n\n\n\n<li>Tension spring<\/li>\n\n\n\n<li>Second washer<\/li>\n\n\n\n<li>Screw on the castle nut<\/li>\n<\/ol>\n<\/li>\n<\/ol>\n\n\n\n<p>You may notice that without the tension from the clutch assembly pushing the pulley wheel against the clutch plate, the pulley spins freely without turning the shaft.<\/p>\n\n\n\n<ol class=\"wp-block-list\" start=\"8\">\n<li>Use a vise grip to tighten the castle nut.<\/li>\n\n\n\n<li>Align the holes in the castle nut with the hole in the shaft for the cotter pin.<\/li>\n<\/ol>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><a href=\"https:\/\/ddmgaragedoors.com\/blog\/uploads\/2022\/12\/aligning-the-castle-nut-with-the-hole-underneath-1.png\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/ddmgaragedoors.com\/blog\/uploads\/2022\/12\/aligning-the-castle-nut-with-the-hole-underneath-1.png\" alt=\"Using a vice grip to turn the castle nut until the hole for the cotter pin lines up with the hole in the shaft\" class=\"wp-image-5549\" width=\"469\" height=\"403\" srcset=\"https:\/\/ddmgaragedoors.com\/blog\/uploads\/2022\/12\/aligning-the-castle-nut-with-the-hole-underneath-1.png 914w, https:\/\/ddmgaragedoors.com\/blog\/uploads\/2022\/12\/aligning-the-castle-nut-with-the-hole-underneath-1-300x258.png 300w, https:\/\/ddmgaragedoors.com\/blog\/uploads\/2022\/12\/aligning-the-castle-nut-with-the-hole-underneath-1-768x660.png 768w\" sizes=\"auto, (max-width: 469px) 100vw, 469px\" \/><\/a><figcaption class=\"wp-element-caption\"><strong>Aligning the castle nut with the hole underneath<\/strong><\/figcaption><\/figure>\n\n\n\n<ol class=\"wp-block-list\" start=\"10\">\n<li>Then, reinsert the cotter pin.
